COMBINED SAW JOl-NTER AND GAGE.

sBncIFIcA'rroN forming part of Letters recent no. 690,668, dated January7, 1902.

Application filed August 6, 1901.;

To aZZ whom it may concern:

Beit known that L-DAvID W. SOLOMON, a citizen of the United States,residing at Arlington, in the county of Snohomish and Stare 0fWashington, have 'invented certain new and useful Improvements in aCombined Saw Jointer'and Gage, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to saw jointers and gages particularly intendedfor use upon crosscut-saws.

The object of the invention is to provide such an implement of strongand simple construction where the several parts are accuratelyadjustable to suit the saw being operated upon to accomplish the desiredresults, and particularly to provide means for jointing thecutting-teeth of the saw to uniform lengths transversely of the saw andto a fair curve or arc of a circle longitudinally thereof, such meansincluding the file-bearing supports and clamp adjustably mounted to theimplement-stock,whereby the saw can be put into such perfect conditionas to insure its running true or straight, a result unattainable byother saw-jointers now in use. This object is accomplishedin theconstruction and combination of parts hereinafter fully described andwhich is illustrated in the accompanying drawings, in which- Figure 1 isa front elevation of the implement. Figs. 2 and 3 are respectively planand end views thereof, and Fig. 4t is a crosssection on line 4 4 ofFigs. 1 and 2. v

The body or stock a of the implement consists of a frame having a seriesOf horizontal laterally-projecting strips b and c integral with anddisposed upon theopposite sides of lthe vertical web w thereof and facedso as to present a fiat surface on each side of .the web for the saw tobear against while being Operated upon. At the upper edge of the stock Yis a iiange d,which projects transversely from w are stationary, whilethe others, f, are vertically movable andformed of pins extendingthrough holes provided and secured to any serial No. 71,044. N0 man.)

i set position by screws g inserted in threaded 1 apertures in the endsof the said fiange.

A filet is held against the said file-supports by a clamp havi u g aclam p-screw h,whi`ch extends through the clamp-yoke j and seats uponthe top of the stock. The yoke straddles the iiange 'd and engages withthe file by the inwardlyprojecting toesk, formed on the extremities ofits pendent legs, overlapping and embracing the-same. As les are usuallymade tapering, the aforesaid clamp is positioned, preferably,

to one side ofthe mid-length of the stock, so that when the file is inthe implement and tension put thereupon the file will be bent to a truearc of a circle and, to p rovide for saws of'different thickness in theblade-that is,A where they tapertoward their back edgethe file isinclined so as to bring the face thereof at right angles to the mediumline of the sawblade when resting against the bearing-'strips baforesaid, and that the strain upon the iile will be equally distributedupon its supporting-points, so as to prevent any twist of the file, Itaper the bearing end Z of the clampscrew to allow a slight tilt orswing to the clamp to correspond with any change in the plane ofthe saidsupporting-points.

m is a pin protruding through a hole in the top of the stock and securedtherein by a binding-screw n, so as to be adjustable for use as agage-point when swaging the saw raker-teeth, the iile being removedduring this operation and the cutting-teeth, which have been previouslyjointed, rest against face-plates o of hard steel.

After the raken-teeth have been swaged to the gage height the implementis reversed and the strips c brought to bear against the blade of thesaw, so that the face-plates 1o will rest upon the cutting-teeth, andeach of the rakerteeth is successively inserted in the oblong aperture rof the block s to be individually jointed by drawing a file thereacross.

What'I claim as new, and desire to secure by Letters Patent, is n l. Ina device of the class described, in combination with a frame having aseries of sawbearing strips disposed upon opposite sides of the webthereof, a iile-supporting ange extending along one of the longitudinaledges of said frame and projecting transversely outside of the plane ofthe said saw-bearing roo strips upon one side of the frame-web, anadjustable swage-gage extending through said flange, another flangedisposed upon the opposite diagonal longitudinal edge to the aforesaidflange and extending transversely outside of the plane of thebearing-strips upon that side, a raker-tooth jointing-block having anoblong aperture extending therethrough attached to the last-namedflange, and a file, of means to secure the said file to the saidfile-supporting Harige so that the file can be bent to an arclongitudinally of the frame and of the entire length thereof, and meansVto change the inclination or slant of the file transversely of theframe, such means including a clamp having a yoke which straddles theupper portion of the frame with inwardlyprojecting toes at the lowerextremities thereof to overlap and engage the said file and aclamp-screw which extends through the yoke and bears upon the frame, andsupports for said file positioned beneath the file-supporting flangeadjacent to the ends thereof two of said supports being adjustable as toheight, substantially as described.

2. In a device of the class described,in coinbination with a file, aframe having a series of saw-bearing strips disposed upon the webthereof, and a iiange extending along one of the longitudinal edges ofsaid frame and projecting outside of the plane of the saidbearing-strips transversely of the frame; of supports for said filecomprising two fixed bearings and two adjustable bearings disposed,respectively,upon the inner and outer edges of the said flange and aclamp straddling the said fiange and adapted to dravT the vile againstthe said supports, substantially as and for the purposes set forth.

3. In a device of the class described, in combination with a frame and atile, of'adjustable bearing-supports for said file comprising pinsextending through a flange of said frame and binding-screws for securingsaid supports to any set position.

In testimony whereof I aiix my signature in presence of two witnesses.

DAVID W. SOLOMON.
